Summary: Regular data collection/cleaning, field still flooded but water level dropping, dropped USB dongle in water

Bouldin Corn

Robert and I arrived at 14:05 PST. It was cold and breezy with thin high clouds. The water level is a little lower on our field—only ankle height rather than shin height under the tower.

I downloaded met, cam, USB GHG, PA, and IRT data. No FD data for now; we are waiting for the water level to go down more before we put the FD chamber back out again. Robert cleaned flux and rad sensors. The reservoir was mostly full, so we did not refill it.

I dropped the USB dongle in the water under the tower while I was packing up my backpack, so I didn’t check the live GHG data at Bouldin Alfalfa or Hill Slough today. I retrieved it but it's wet so I don't want to plug it into anything just yet.

The 7500 read: 430ppm CO2, 322mmol/m3 H2O, 13.0C, 102.2kPa, 101SS—102 after cleaning
The 7700 read: 2.1ppm CH4, 50RSSI --> 80 after cleaning

We left at 14:35 PST.
